In addition, nanotopology, mircoRNAs, etc. regulate the expression of a variety of osteogenic and chondrogenic transcription factors through up- and down-regulation of KDMs. In summary, the role of histone demethylase in the osteogenic and chondrogenic differentiation of mesenchymal stem cells will help us better understand the pathogenesis of bone and cartilage damage diseases, and establish the foundation of future clinical applications for bone and cartilage tissue engineering.Hydroxyapatite (HAp) is the main inorganic component of the bones and teeth, and it possesses bioactivity and biocompatibility. However, due to its poor mechanical performance, slow degradation speed, and lack of diversity in its function, it is difficult to apply HAp alone as a scaffold material for bone tissue engineering. By combining HAp with other types of materials, composite materials with specific properties can be prepared, and the scopes of HAp applications can be expanded. Firstly, we elaborated on the importance, and strengths and weaknesses of HAp for bone tissue engineering biomaterials and then reviewed the research status of HAp composite materials used in bone regeneration. Secondly, about hot research topics in the field of applying HAp composite materials in bone repair, we summarized the representative findings in the field, and discussions and analysis were made accordingly. Finally, we also examined the future development prospects of HAp composite bone repair materials.Modern tissue clearing techniques have made it possible to have high-resolution imaging of cell populations and three-dimensional reconstruction of tissue structures, and we are able to obtain more complete three-dimensional brain structures and spatial connections between the various components of brain tissues through tissue clearing techniques. Over the past decade, scientists have developed and improved a number of tissue clearing techniques that are now widely used in neuroscience research, allowing us to extract important information from complex neural networks. Moreover, tissue clearing technology also provides research tools for the stem cell therapy and neurogeneration of neurodegenerative diseases. In this paper, we reviewed the major types of existing tissue clearing techniques and their respective strengths and weaknesses. We summarized the application of these techniques in neurodegenerative disease research and their unique merits. In addition, we explored the development requirements of tissue clearing technology, improvements in the supporting equipment, and its potential to be used as research tools for stem cell therapy and regenerative medicine in the future.In recent years, tetrahedral framework nucleic acids (tFNAs) have become a hot topic in the field of DNA nanomaterials due to their excellent mechanical, chemical and biological properties. Selleck MYCi975 By taking advantage of these merits, tFNAs of varied sizes and modification methods have been designed and applied in diverse fields such as regenerative medicine, biosensors, and tumor treatment to promote human health. This paper reviews the current research progress of tFNAs in human health-related fields, and the future challenges in the clinical applications of tFNAs.
Leukemic stem cells (LSCs) play an important role in the pathogenesis of leukemia. This research attempted to clarify effects of the telomere system on ginsenoside Rg1-induced senescence of LSCs.

This research attempted to clarify effects of the telomere system on ginsenoside Rg1-induced senescence of LSCs.

CD34+CD38- LSCs were isolated, sorted, and divided into a control group and a Rg1 group (treated with 40 μmol/L Rg1). Cell Counting Kit-8 (CCK-8) was used to evaluate cell proliferation, and flow cytometry was used to assess the cell cycle of CD34+CD38- LSCs. The SA-β-Gal staining and CFU-Mix assay were conducted to measure senescence of CD34+CD38- LSCs. The mRNA transcription and protein expression of p16INK4a and human telomerase reverse transcriptase (hTERT) were determined using a real-time polymerase chain reaction (RT-PCR) and western blot assay, respectively.

The Rg1 treatment significantly attenuated proliferative activity and decreased the proliferative index (PI) of CD34+CD38- LSCs comparnt of leukemia by providing a promising strategy to induce senescence of CD34+CD38- LSCs.
Myocardial ischemia/reperfusion injury (MIRI) usually induces serious health problems.

This study attempted to explore protective effects of (-)-epigallocatechin-3-gallate (EGCG) on MIRI and the associated mechanism.

Ischemia/reperfusion of an isolated rat heart (I/R model) and the MIRI model were used in this study. Myocardial infarction was measured with staining with 2,3,5-triphenyltetrazolium chloride (TTC). Ca2+ and Tn-T concentrations in coronary perfusion fluid were evaluated using the chromatometry method. Ca2+ concentration in cardiomyocytes was determined with detecting Ca2+ fluorescence intensity. The ultrastructure of cardiomyocytes was observed using transmission electron microscopy (TEM). β-nicotinamide adenine dinucleotide (NAD+) of cardiomyocytes was also determined.

The EGCG (I/R+EGCG) significantly reduced myocardial infarction size of isolated rat heart compared to I/R rats (p < 0.05), remarkably increased Ca2+ and decreased troponin T (TnT) concentrations in coronary perfusion fon size in both I/R models and MIRI models by reducing intracellular Ca2+ concentration, increasing TnT concentration, promoting NAD+ concentration, and improving the ultrastructure of cardiomyocytes.
Although long non-coding RNAs (lncRNAs) have been reported to serve as potential biomarkers of atherosclerosis (AS), the role of lncRNA small nucleolar RNA host gene 12 (SNHG12) in AS still remains to be elucidated.

The present study aimed to investigate the regulatory effects and potential mechanisms of SNHG12 in human vascular smooth muscle cells (hVSMCs).

Reverse-transcription quantitative polymerase chain reaction (RT-qPCR) was employed to determine the expression of SNHG12, miR-766-5p and eukaryotic translation initiation factor 5A (EIF5A) in oxidized low-density lipoprotein (ox-LDL)-induced hVSMCs. After transfection with short hairpin RNA (shRNA)-SNHG12, cell viability was estimated using the Cell Counting Kit-8 (CCK-8) assay. Wound healing and transwell assays were used for evaluating migratory capacities of hVSMCs. To further investigate the regulatory mechanisms, binding sites between SNHG12 and miR-766-5p, and EIF5A and miR-766-5p were predicted using starBase database and validated using luciferase reporter gene assays.
